What is a benefit of ground covers in landscapes?

Ground covers serve several important functions in landscaping, and one of the primary benefits is their ability to reduce soil erosion. By establishing a dense mat of vegetation, ground covers help to stabilize the soil with their root systems. This is particularly valuable on slopes or areas prone to water runoff, where soil can easily be washed away during heavy rainfalls. The foliage of ground covers further protects the soil by reducing the impact of raindrops and slowing down water movement, which assists in retaining moisture and nutrients in the soil.

Other options, such as increasing sunlight exposure or attracting pests, do not represent advantages of ground covers. Similarly, while maintenance is necessary for any plant, ground covers are often chosen for their lower maintenance requirements compared to other landscape plants.
